WINDING MECHANISM FOR MUSIC SHEETS.

SPECIFICATION forming part of Letters Patent N 0. 647,086, dated April10, 1900.

Application filed December 15,1899. $erial No. 740,885. (No model.)

To all whom it may concern:

Be it known that I, FRED R. GOOLMAN, a citizen of the United States, anda resident of St.Johnsville,Montgomery county,New York, have inventedcertain new and useful Improvem cuts in WindingMechanism for Music-Sheets, of which the following is a specification. a

This invention relates to an improved winding mechanism for perforatedmusic-sheets, such as is used for drawing the sheets over the air-ductbridge of a pneumatic piano and for other purposes.

Theinvention has for its objects to cause an automatic rewinding of themusic-sheet from the receiving-drum upon the delivery-spool when thepiece has been played, to automatically arrest the motor when the sheethas been thus rewound, and to start the motor when a new sheet has beenproperly adjusted.

In the accompanying drawings, Figure 1 is a plan, partlyin section, ofmyimproved apparatus; Fig. 2, a detail of spindle a Fig. 3,

an end view of head a; Fig. 4:, a section on line 4 l, Fig. 1; Fig. 5, asection on line 5 5, Fig. 1; Fig. 6 a section on line 6 6, Fig. 1; andFig. 7, a section through a modification of the delivery-spool a.

The letter a represents the delivery-spool, to which one end of themusic-sheet b is attached by being pasted around such spool, Fig. 6, orby being secured within a slot of the same, Fig. 7. The sheet 1) passesover the air-duct bridge 0 or other means for actuating thesound-producers of a musical instrument, and thence to thereceiving-drum d. This drum is provided with a circumferential groove d,which serves for the reception of a resilient or hinged circuit-closin garm e,which when moved outward engages a contact-bar e to close anelectric circuit and start the motor that rotates the drum d.

In use the end of sheet I) is attached to drum d and is wound partlyaround the same by hand, so as to cover groove d and force the arm coutof such groove and into contact with bar a, so as to place the motor incircuit. This motor by suitable transmitting mechanism-such, forinstance, as described in Patent No. 603,184, granted to me April 26,1898, and which is reproduced in the present applicationrotates the drumd upon turning a knob and thus draws the music-sheet over bridge 0.Briefly stated, this transmitting mechanism consists of the power shaftf, driven from the motor by pulley f and imparting motion bycone-pulleysf f and pinion f 4 to the gear-wheel d of drum d. When thesheet I) has been wound completely upon drum d, the reversing mechanismis automatically started by means hereinafter described to rewind thesheet upon spool a, and thereby uncover groove d. This will release arm(2 and cause it to reenter the groove and break the circuit to stop themotor as soon as the sheet has been completely rewound.

The reversing and rewinding mechanism is of the following construction:The spindles a a of spool a turn in a swinging frame 9, pivoted to fixedsupports at g and engaged by set-screw g, which limits the tiltingmotion of the frame. The frame 9 is provided with an arm g rigidlyconnected to the frame g and engaging a slide 9 that in turn engages aclutch or shifting device. As soon as sheet I) has been completely woundon drum d it will exert a strain or pull on spool a and willconsequently tilt or oscillate frame g, Fig. 6, to actuate the clutch orshifting device.

The shifting device is so constructed that when actuated it will at onceuncouple drum (1 from driving-shaft f and will couple spool a to suchshaft by a crossed belt, so that the spool a, will rotate backward andwill thus rewind the sheet b upon the spool. When the drum d has beenbared from the sheet, the contact 6 6' will be broken in the mannerpreviously described and the motor stopped, so that the rotation ofspool a ceases the moment the sheet has been rewound.

The clutch or shifting device for actuating the rewinding of the sheetupon the tilting of frame 9 may be of suitable construction and issimilar to that shown in Patent No. 603,184, above referred to. Brieflystated, the slide g tilts upwardly a'pivoted frame it, that liberates aspring-actuated shifting lever h and throws a hollow shaft 2', by spring2", into engagement with collar f of shaft f. The hollow shaft 2'carries the pulley i which by crossed belt 1' and pulley a rotatesspindle a of spool a to thus rotate such spool backward. The normaltension of the belt 1 will not tilt the frame 9 oil": the set-screw g,because the latter should be so adjusted that the center of the spindlea is in the same horizontal plane or below the center of the fulcrum g.The shifting lever h also moves a slide j, which by wedge j throwssidewise the cone-pulley f and disengages pinion f from gear-wheel d touncouple drum d from shaft f.

After the sheet has been rewound upon spool a the latter may be removedand replaced by a spool carrying a new sheet, which is partly wound upondrum (1, as already described, to reestablish contact a e, and then thecone-pulley f and slide j are returned to their normal position byturning knob It) on rod 76 to restart the instrument.

The spool C6 is rotatably mounted upon the spindles a a in the followingmanner: The head (t of the spool has a pair of notches a adapted toengage a pair of pins (L6 on spindle a. The end of spindle (t issurrounded by a rotatable cap Z, held thereto by a groove and a pin athe cap being adapted to be received within a corresponding socket ofhead (6 The spindle a is normally pushed inward by a spring a" to holdthe spool in place. To unseat the spool, it is moved toward the left byhand to crowd the spindle a outward and disengage the head a from pinsa.

What I claim is- 1. In a winding mechanism for music-sheets, areceiving-drum having a groove, combined with a spring-contact\adaptedto normally enter said groove, and with a music-sheet adapted to bewound upon the drum and displace said contact, substantially asspecified.

2. In a winding mechanism for m usic-sheets, a receiving-drum having agroove, a springcontact adapted to normally enter said groove, a secondcontact a motor in circuit, and a music-sheet adapted to close thecircuit when wound upon the drum, substantially as specitied.

3. In a winding mechanism for music-sheets, the combination of aswinging frame with a delivery spool hung therein, a receiving drum, amusic-sheet attached to the spool and adapted to be wound upon the drumconnections whereby the frame is tilted by the tension of the sheet, aslide connected to the frame, a motor adapted to be coupled to the drum,and a shifting device actuated by the slide and adapted to couple themotor to the spool and uncouple it from the drum substantially asspecified.

4-. In a winding mechanism for music-sheets, the combination of adelivery-spool with a swinging frame, a grooved receiving-drum, acontact normally entering said groove, a motor in circuit when thecontact is forced outward, a music sheet secured to the spool andadapted to be wound upon the drum, and means for uncoupling the motorfrom the drum and coupling it to the spool upon the tilting of theframe, substantially as specified.
